ckeeler11 Posted June 10, 2016 Report Share Posted June 10, 2016 In Torres with the box size you have in the 12volt calculator i get a box net volume of 5.25 cu.ft. and a tune of 38 Hz. the problem is neither of the above calculators take into account the net volume of the box after port, sub and bracing displacement. to get you a tune of 28 Hz at 7 cu.ft your external dimensions need to be atleast 24x25x35 with a port 4x25x38 in. long Link to comment Share on other sites More sharing options...
Jessica Posted June 10, 2016 Report Share Posted June 10, 2016 how many common walls does your port have? how many walls are part of the box, how many are not. That is important Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside. My super random youtube channel and terrible camera work.

Jessica Posted June 10, 2016 Report Share Posted June 10, 2016 40" would be the length, but why tune so low? Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

xpoppadaddyx Posted June 10, 2016 Author Report Share Posted June 10, 2016 40" would be the length, but why tune so low? Just going by what this program is saying. However, it's saying tune lower for my drivers.

xpoppadaddyx Posted June 10, 2016 Author Report Share Posted June 10, 2016 how many common walls does your port have? how many walls are part of the box, how many are not. That is important I'll be porting at the bottom of the enclosure and the subs baffle will be on the top. So the port should share the sides of the box. 2002 Chevy Trailblazer (Build) 2013 Nissan Altima (Build) Poppa's YouTube Channel Poppa's FB Page Poppa's Instagram Link to comment Share on other sites More sharing options...
